Free radical or oxidative damage is strongly linked to aged-related macular degeneration (AMD), the leading cause of blindness in Canada. Therefore, researchers believe that antioxidants such as vitamins C and E, bilberry, lutein and selenium may play a key role in prevention and treatment. Another potent antioxidant, coenzyme Q10 (CoQ10), was the subject of two [...]

A new study from Ohio State University showed that lutein and zeaxanthin, antioxidants found in plants such as kale, spinach and collard greens, helped to protect the cells from exposure to ultraviolet light — a leading cause of cataract formation. The researchers compared the effects of these antioxidants to vitamin E and found that lutein [...]

A healthy fat found in fish oil (docosahexaenoic acid, or DHA), may slow the rate of vision loss in people with an eye disease known as retinitis pigmentosa (RP). RP is a group of diseases that affect the retina, leading to night blindness, tunnel vision, and possible total blindness. DHA is necessary for proper vision [...]

A new study from Ohio State University provides the first laboratory evidence that certain antioxidants found in dark leafy green vegetables can indeed help prevent cataracts. Results from experiments on human lens cells showed that lutein and zeaxanthin, antioxidants found in plants such as kale, spinach and collard greens, helped to protect the cells from [...]

In the largest study to date examining the relationship of diet to dry eye, researchers at Harvard Medical School have discovered that getting more omega-3 fatty acids can help prevent and relieve the dry-eye symptoms experienced by millions of North Americans. The study, presented at the Annual Meeting of the Association for Research and Ophthalmology, [...]

Lutein is a naturally occurring plant pigment found in a number of plant foods, including corn, spinach, kale, romaine lettuce, peas, leeks and collard greens. When we ingest lutein, whether through foods or supplements, it concentrates in a section of the eye called the macula, a small area of the retina. Studies show that lutein [...]

When was the last time you “looked” at your diet with respect to how it may be helping or hurting your eyes? Most of us don’t think about vision health until it’s too late, and cataracts or age-related macular degeneration (AMD) are already setting in. However, foods or supplements that supply adequate antioxidants and the [...]

Pycnogenol is a patented extract of maritime pine bark. Like grape seed extract, pine bark belongs to a class of nutrients in the flavonoid family called proanthocyanidins. These compounds have antioxidant activity and play a role strengthening connective tissues, including those that support blood vessels. For this reason, pycnogenol has been found helpful in treating [...]

Over the past few years, studies have suggested that greater consumption of lutein, a “cousin” to beta-carotene that’s found in dark green, leafy vegetables, may protect against a leading cause of vision loss in the elderly. Research now suggests that lutein may offer multiple benefits. Lutein (“LOO-teen”) is a member of the carotenoid family that [...]
